MAINTAINED-OIL-LEVEL-REGULATING DEVICE.

Application filed. March 10, 192 1. SerialNo. 451,388.

' is a specification.

This invention relates to maintained oil level regulating device, and the like. I

The object of my invention is to mamtain a constant, uniform, and unobstructed flow of oil to the burner.

A further object of my invention is to construct an oilcontrolling device which 1s to be placed beneath the oil reservoir, which will maintain aconstant level in the burner.

A further object of the invention is to arrange a reservoir in the oil controlling device With such relation to the base support ing them that the moving of the reservoir proper up or down will regulate the height of the oil in the burner.

A further object of the invention is to arrange a sight feed adjacent the burner, whereby the operator may readilyv see the height of the oil in the chamber adjacent the burner preparatory to starting the device.

In the accompanying drawings:

Fig. 1 is an elevation partly in section disclosing my heating system complete;

Fig. 2 is an enlarged transverse section of the controlling mechanism;

Fig. 3 is a top plan view of the burner and visible feeding device adjacent thereto;

Fig. 4 is a modified form of the reservoir;

V Fig. 5 is a modified view on the line 5-5 of Fig. 1 of the oil feed-pipeadjacent the burner.

The numeral A. indicates the main supply tank; B, the auxiliary supply tank or reservoir; C, the. valve controlling mechanism; and D, the burner. The auxiliary I reservoir or supply tank consists of a cylidrical receptacle dvided into upper and lower compartments 1 and 2, being separated by a transverse disk 3.- The upper end of the compartment 1 is open and adapted to receive the main supply tank A, while heavy cloth,'over which is placed a quantity of cotton batting or other similar material 7.

The partition 3- is provided centrally thereof with a downwardly projecting nip- Plc 8, having a small central opening 9 terminating at the lower end thereof in a valve-seat 10. The numeral 11 indicates a float constructed of cork or other suitable material located in the lower compartment 2. In the central opening 12 of the float is arranged a valve-stern 13 made integral with a metal disk 14, the latter being secured to the lower side of the float l1 and provided concentrically with a stem 13 and. with a plurality of openings 15. The upper end of the valve-stem 13 is countersunk and adapted to receive a high-grade perfect steel ball-valve 16, the ball adapted to seat itself about twothirds of its diameter in the valve-stem 13. By this construction, when the fuel has risen a suflicient height in the lower compartment, the ball-valve will actto cut off the supply from the upper compartment.

The auxiliary reservoir is preferably supported upon a base 17 provided with a hollow threaded portion 18 adapted to receive the hollow threaded stem 19 secured to'the bottom of the reservoir 1 by a reinforcing member 20.

The numeral 21 indicates a threaded disk or locking-nut received upon the liollo v threaded stem 19, the former being countersunk on the under side and adapted to receive. a leather washer 22 which is provided with internal screw-threads, thereby effecting a tightfit between the stem anl the lock ing-nut 21. p

Leading from the base 17 is a feed-pipe 23, to the outer end of which is connected a burner support consisting of a hollow upright portion 2a somewhat enlarged at the upper end thereof, forming, an oil chamber 25, which preferably provided with a removable cap 26. This cap may or may not be transparent, the purposebeing to provide adequate means for determining the oil level Within the chamber 25.

The numeral 27 indicates a burner pro vided with an annular oil groove 28. Extending horizontally from the oil chamber 25 is an oil duct 29 provided with a small centralbore 30, said bore preferably in line with the bottom of the annular oil groove 28. As shown in Fig. 5, this oil duct may lll) be in the form of a tube 29, having arranged therein a plug 30 having a longi tudinal slot 31 acting in the same capacity as the opening 30.

As a means for cleaning the oil duct 29, I preferably arrange an opening 31 diametrically opposit thereof inthe chamber 25, which, however, is normally closed by a plug 32, the removal of the plug permitting of an instrument being forced into the opening 30 for cleaning purposes.

As a further convenience, the plug 32 may be replaced with a drip-cock for draining off the chamber 25, slrould the oil rise suddenly.

In Fig. 4 is disclosed a modified form of the oil container" or reservoir 1, wherein the upper compartment 1 is removably suspended within the main oil container 1,,and the float or valve-controlling mechanism 11 is located therebeneath, both elements being readily removable.-

In operation, the reservoir 1 is adjusted to such a height with respect to the supporting base as to bring the oil in the compartment containing the float on a level with the opening in the oil duct 29 adjacent the burner, at which level the ball-valve is seated upon the valve-seat 10, cutting off the flow of oil to the lower compartment. To

vary the height of oil in the float compart-.

ment and the oil chamber 25, it is only necessary to adjust the-height of the reservoir 1 with-respect to the base 17. To reduce the oil level in the float chamber, a lock-nut 21 is unscrewed, and the container or reservoir 1 is screwed down or turned to the right,

- while raising or turning to the left will in-.

crease the height of the oil in 'the fioat chamber, and correspondingly increase the flow of oil to the burner, or rather increases the height of the oil in the chamber 25. When the proper height is determined, locknut 21 is screwed down, holdin the container 1 in the adjusted position. It will be observed that the pressure of the oil is against the closing movement of the ball, thereby effecting a very sensitive and reliable action.

I claim:

1. A heater comprising a burner adapted to burn a liquid fuel, a reservoir consisting. of an upper and lower compartment, a filtering means arranged in the bottom of the upper compartment, and a regulating means arranged in the lower compartment for regulating the supply of fuel to the burner.

" 2. A heater comprising a burner adapted to burn a liquid fuel, a reservoir for the liquid, a hollow threaded stem supporting the reservoir, a base having a vertical hollow threaded portion in which said stem is adjustably received and means for holding the stem and the reservoir in any desired adjusted position for controlling the level of oil supplied to said burner.

3. A heater comprising a burner, a reservoir and an oil chamber, bases for the reservoir and for the oil chamber, connection from the base of the reservoir to the base of the oil chamber, a vertical connection eitending between the oil chamber and the base thereof, a horizontal feed line extend;

the upper part of the oil chamber to the burner and means arranged in the lower compartment of the reservoir for maintaining a given-oil level in said lower compartment of the reservoir and said oil chamber.

5. A heater comprising a base, a reservoir consisting of upper and lower compartments arranged above said base, a burner, an oil chamber, a feed pipe connecting the lower compartment of the reservoir to the oil chamber, a feed pipe leading from the upper part of the oil chamber to the burner, means arranged in the lower compartment of the reservoir for maintaining an oil level in said lower compartment and said oil chamber and means for regulating, the height of the reservoir relative to-the base for changing the level oi the oil from the lower compartment of the reservoir with respect to the oil chamber adjacent the burner.

' 6. A heater comprising a reservoir consisting of upperand lower compartments, a burner, an oilchamber adjacent to the burner, a pipe arranged horizontall tween said chamber and burner, a fee -pipe connected to the lower compartment of the reservoir and the oil chamber, means arranged in the lower compartment of the si ature. v
